Allergies
Allergic rhinitis is an allergic reaction that affects the mucous membrane inside the nose. The mucous membrane is the tissue that produces mucus.
There are two types of allergic rhinitis:
-
Seasonal. This type is also called hay fever and happens only during certain seasons of the year.
-
Perennial. This type can happen at any time of the year.
Allergic rhinitis cannot be spread from person to person. This condition can be mild, bad, or very bad. It can develop at any age and may be outgrown.
